This invention relates to metallic trim or ter'- minal reinforcement of handles.

This invention has utility when incorporated in ferrule mounting of wood handles for tools.

Referring to the drawing:

Fig. 2 is a View of the ferrule formed from the blank of Fig. 1;

Fig. 3 is a section on the line III-III, Fig. 2;

Fig. 4 is a view of a. roller press for completing assembly of the ferrule of Fig. 2 with a wood handle;

Fig. 5 is a fragmentary View of a wood handlehaving the ferrule assembly therewith eifected by the press of Fig. 4;

Fig. 6 is a section Fig. 7 is a view of handle of Fig. 5; and

Fig. 8 is a section on the line VIII-VIII, Fig 7.

Sheet metal blank is shown with body portion I having tongues 2, 3, therefrom. The free ends of these tongues are shown as having lateral extensions This blank isformed into a ferrule by having weld assembly of edges 5 of the body portion, thereby forming tapered tubular portion 6, from which extend the tongues 2, 3, with the lugs 4 having weld I completing such as a spacing means or ring for the free ends of the tongues and leaving open work t between the tongue termini as remote from the tapered body portion 6 of the ferrule.

Wood handle 9 having tapered portion I0 may have such tap-ered portion telescope into the tapered portion` 6 of the ferrule for tting assembly therewith. The tongues 2, 3, as well as the rings 4, 1, are of an extension from the body portion of the ferrule and desirably do` not conform in shape or dimension with cylindrical portion i I of the handle 9 as extending from its tapered portion I9.

In carrying out the invention herein, base I 2 is shown mounting brackets I 3 providing iixed bearings for shaft I 4 having pulley I5 thereon driven by belt I6. Mounted on bearing Il fixed with the base I2 are links I8 providing bearings for shaft I9 parallelism with the shaft I4. The base I2 is shown provided with diameter gages 29 at respective grooved roll pairs 2|, 22, on the shafts I4, I 9. In practice, say in wood handles for shovels, these gages 29 may vary, say elf of an inch. If the sheet metal for the ferrule be say twenty gage, at the gage 29 for the diameter II of the wood handle 9, as determined by the operator, position is located. For such wood on the line VI-VL Fig. 5; the assembled ferrule and desirable to select, with handle proper assembly of ferrule therewith, it is gage No. 20 metal, 31, inch larger diameter. This would be to the left, as. the graduation is shown in Fig. 4, as the one wherein there is to be inserted the handle terminus Ii) from which the cylindrical portion II extends.

With this pair of rolls 2l, 22, rotating away from the operator at their portions toward each other, this terminus I9 may be inserted in clearance region 23 with roll anges 2d rst acting at diametrical portions to roll reduction in diam- I eter at this region approximating parallelism with the shafts I4, I9, and this reduction progresses therefrom as plane of the pair of shafts I4, I9. The tongues 2, 3, have marginal offsets 25 embedded in the wood of the handle 9 as the rollers 2l, 22, progress the ferrule therebetween in changing from oval to cylindrical form.

As the ring t, 1, comes into the region of reduction, there is peripheral collapsing, which in practice seems to compact the metal generally throughout the cylindrical region, even with absence of puckerings or irregularities. Due to these spacings between the free ends of the tongues 2, 3, the diametrical relationship of the tongues is held against shifting and there is thus accurate location thereof on the handle as the collapsing of this ring into partial or semi-embedding relation with the wood of the handle oocurs. This effects an anchorage against axial shifting of the ferrule as to the wood handle and it is an anchorage effected in a single operation with accuracy in form and tting independently of weakening the stock of the wood as by perforation.

On the shaft IE is pulley 26 to be driven by belt 2l so that both shafts Ill, i9, are alive or driven shafts in urging the stock through for the collapsing or assembly herein set forth. From this shaft l 9 links 28 may extend to treadle lever 29, depression of which against the action of springs 30 brings the clearances 23 into true circle form, while release of the treadle 29 causes the springs 39 to increase the spacing from the shaft I9 to the shaft I6, thus freeing the formed article from the device so that the operator may readily remove such therefrom. The wood handle 9 with the ferrule compacted therewith as to the portions away from the tapered region is thus an effective terminal trim and reinforcement which may have a terminal keying 3l for receiving tang of a tool, such as a fork, spade, hoe, or similar device.

The departure from tting form of the extenthe stock moves into the sions 2, 3, 4, from the tapered sleeve 6 permits ready slipping of the tapered portion 6 into snug seat-fitting with the tapered portion l0 of the handle 9, even about the bend in the handle between the portions ID, Il. The roll collapsing effecting the embedding of the tongue edges 24 and the ring 4 is a bringing of this departurefrom-fitting portion into snug, conformed assembly, even against weathering attack for the handle at such joining. This holding is of tightness even resisting loosening at expansion and contraction from heat as to the metal or moisture as to the wood in such degree that there is no weakening, but this embracing to conform is a substantial reinforcement of the wood eliminating any weakening regions for the handle as toward the tool.

The rolling reduction in bringing the extension from the tapered portion into fitted configuration with the wood handle produces an assembly which even as exposed to weathering does not have rough edge or margin projections tending to wound the hand of the operator or tear or unduly wear the hand coverings of the operator.

What is claimed and it is desired to secure by Letters Patent is:

A sheet metal ferrule of symmetrical outside and inside contour throughout, said ferrule comprising a tapered, annularly complete, tubular section; axially spaced therefrom an additional exteriorly and interiorly annularly-continuous, complete cylindrical section; and approximately parallel independent laterally spaced tongues integral with and connecting said sections providing openings between the sections, said openings being parallel and spaced by the tongues.
